If the eyepiece has a magnification of 10x, what would be the total magnification of an image if you were using the lower power objective? (how do you figure this out?)
To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.
